To work around this when I just don't have time to restart Revit, I use a Windows accelerator key combination. Select a view with collapsed dependant views under it. Hold down the Alt key and press the * (asterisk) on your num pad. This will expand every view below it. Alternatively you can hold down the Alt key and press the - (minus) key on the num pad collapse all the views under it. Only the * and - on the num pad work.
It's a Windows thing, so give it a shot in Windows Explorer on anywhere files are listed.
